'Salt has adsorption properties, which means that it can bind to moisture and prevent it from developing condensation. This is why salt is often used in the kitchen to stop water droplets from forming on dishes or silverware,' explains homecare expert and archeologist Barry Gray from The Tool Square.
A savvy mum has revealed a simple way to stop condensation on your windows for just 65p - by using salt. Nazia Safa discovered that leaving a bowl of salt on the window sill overnight stops moisture seeping through the glass.
Another added: "Leave a little pot or two of salt on your window sill. It draws the moisture. Just put a fresh pot/bowl out each night.”
Rock salt naturally absorbs moisture out of the air, making it a great choice to use as a dehumidifier. To make a rock salt humidifier, you'll need a large bag of rock salt (also sometimes referred to as sodium chloride) and two 5-gallon buckets. You should be able to find both at a hardware store.
If solving your moisture problem is something you'd like to do inexpensively, rock salt may be your answer. Because rock salt is hygroscopic it absorbs moisture from the air. If your plan is to get rid of the humidity in a damp basement, start with a 50-pound bag of sodium chloride to make your rock salt dehumidifier.
Answer: Technically, salt draws out moisture through the process of osmosis. This is the basis for all the theories about drying and toughening properties of salt when in contact with foods.
Use dehumidifiers and air conditioners, especially in hot, humid climates, to reduce moisture in the air, but be sure that the appliances themselves don't become sources of biological pollutants. Raise the temperature of cold surfaces where moisture condenses. Use insulation or storm windows.

If you wake up and find condensation on your bedroom windows, a great way to clear away the condensation is by mixing a home-made solution. Simply mix two cups of water and two cups of white vinegar, then add a couple of drops of washing up liquid.
To stop condensation on windows at night try keeping your bedroom door open to improve airflow and leaving your curtains open, or swapping for a thinner material. If this doesn't fix the problem, check the seals of the windows (as mentioned above) or consider running a dehumidifier at night to keep moisture at bay.
One of the most promising salts is calcium chloride because of its excellent water sorption properties in combination with a natural and industrial abundance. The salt is able to absorb more than 95% of its own weight in water for the reaction of the anhydrous salt to the hexahydrate.
The reason being that salt kills many single cell organisms, including mold spores, by dehydrating them. Salt is therefore thought to be an effective mold killer, for the same reason honey is thought to be an effective mold killer—salt absorbs moisture.
This means that salt is hygroscopic, so it absorbs both liquid water and water vapor present in air. Table salt becomes wet because it absorbs water and water vapour present in the air and it's hygroscopic in nature. It absorbs moisture from the atmosphere which contains high humidity in rainy season.
Get a dehumidifier
In contrast to a humidifier, a dehumidifier will remove moisture in your home and absorb condensation.
Table salt becomes sticky on exposure during the rainy season because table salt generally contains a small percentage of magnesium chloride, as an impurity. Since, these impurities absorb moisture from the air due to their deliquescent nature; therefore it gets wet in the rainy season and becomes sticky.
You can use baking soda to naturally dehumidify a room that has high-moisture levels. Simply fill a small bowl with baking soda and place it on the window sill. Over time you will notice the baking soda will harden as it absorbs the moisture.
In most cases, internal condensation issues occur because of too much humidity in the room or little to no air circulation. Low internal room temperatures can also create cold surfaces (particularly on windows and exterior walls) which allows warm air to condense onto them easily.
Calcium Chloride has a much better performance when the relative humidity is high. Calcium chloride increases its capacity to absorb water over time because the absorption process makes the moisture dissolve into the calcium chloride.
Keep bowls of salt in corners of rooms
Place glass bowls containing rock salt in the corners of the room and remove them after 10-12 hours. During this time, the salt will absorb the negative energies present in the house. Then take this salt and throw it away immediately away from the premises.
A salt which changes into liquid state on absorbing water from air is called hydrated salt.
Condensation is the moisture formed when warm, humid air encounters a cold surface. At night, almost all year round, the difference between indoor and outdoor temperatures means that condensation is always a possibility.
